Specification of Letters LPatent.

Patented Sept. 26, 1905.

"Application filed September 3, 1904. Serial No- 223,296.

Be it known that I, JOHN S.' KURTZ, acitizen of the United States, residing in Earl township, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Tongue- Supports, of which the following, is a specification, reference being had therein to the accompanying drawings. V

This invention relates to a support for the tongues of agricultural machines; and its object is to provide a simple, compact, and efficient construction. and arrangement of parts adapted for yieldingly attaching a rolling support or colter-wheel to the tongue of an agricultural or equivalent machine and whereby the angle of the spring-arm .in relation to the tongue can be easily and rapidly varied.

The invention consists, first, in the construction of the end of the spring adjacent to the tongue; second, inthe connection between the spring and the tongue; third, in the construction of the mechanism for regulating the angle between the spring-arm and-the tongue,- and, fourth, in the construction and combination of the various parts, as hereinafter fully described and thenpointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation; Fig. 2, a bottom plan view; Fig. 3, a top view of the whole invention; Fig. 1, a top view of the spring detached; Fig. 5, a vertical section through A A of Fig. 1; Fig. 6, a perspective bottom view of the springhead; Fig. 7, a perspective top view of the spring-head clamp; Fig. 8, a transverse section through the colter-wheel and its connections; Fig. 9, a perspective view of the bushing of the colter-wheel, and FigQlO a side view of the connection between one of the spring-arms and the spindle of the colterwheel.

Referring to the details of the drawings, 1 indicates the tongue, resting upon the bearing-plate 2 of the spring-head.

3 indicates the spring-head, the under face whereof is concave in outline longitudinally of the length of the tongue, and in the face of this concavity there are grooves 4, also disposed longitudinally of said tongue and of the same convexity as the spring-head. There is a convex clamp 5 adapted to engage the concavity of spring-head 3 and having therein the inner fake 7 of the spring-wire, the otherfakes being outside of said spring-head. The outer fake of each spring-coil extends forward and forms a spring-arm 15, supporting one end of-the spindle 9 of the colter-wheel' 10. The grooves 6 of clamp 5 also engage the fakes 7 of coils 8. These parts are bound together by a bolt 11, passing through holes 12 in the tongue, the spring-head, and the clamp and secured below by a nut 13.

'In operation to vary the angle of the springarms in relation to the tongue the nut 13 of bolt 11 is loosened, and the coils'8 are then turned in the grooves of spring-head 3 and clamp 5, after which the nut is tightened up.

The colte r-wheel has passing therethrough abushing 14:, and through the bushing passes the spindle 9, supported at each end by one of the spring-arms l5. Spindle 9 is of the nature of a bolt, the end 16 thereof being threaded. Onthis threaded end the eye 17 of the adjacent spring-arm is separated from the colter-wheel by a washer 18, and outside of said eye is the nut 19.- On the other end of the bolt is an eye 20, between which and said colter-wheel is located a grooved washer 21. The straight end 22 of one of the springarms passes through the groove of washer 21 and said eye 20,;all as shown. End 22 of its spring-arm is secured in place by tightening nut 19. l

1 do not restrict myself to the details of construction herein shown and described, as it is'obvious that alterations may be made therein without departing from the principle and scope of my invention. a

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-, g

1. The c0mbination,in a tongue-support, of the tongue, a spring-arm connected with a colter-wheel, and a coiled spring connecting the spring with the tongue.

2. The combination, in a tongue-support, of

atongue, aspring-head attached to the tongue,

a clamp, a spring-arm connected with a coltera tongue, a grooved spring-head attached to the tongue, a grooved clamp, a spring-arm connected with a colter-wheel, and a coiled spring on an end of the spring-arm and engaging grooves in the spring-head and the clamp.

4. The combination, in a tongue-sup imrt, of

a tongue, a grooved spring-head attached to the tongue, a grooved clamp, a spring-arm connected with a colter-wheel, and a coiled spring on an end of the spring-arm and hav- 1ng one fake thereof engaging a groove in the spring-head and a groove in the clamp.

der face with a groove therein, a convex clamp having a groove in the convex face, a springarln connected with a colter-wheel, and a coiled spring on an end of the spring-arm and having a fake thereof engaging the grooves in the spring-head and the clamp.

a tongue, a spring-head having a groove on each side thereof, a clamp having correspond- 1 ing grooves, two spring-arms connected with a colter-wheel and a coiled spring on an end head and of the clamp. 5. The comh1nat1on,1n atongue-support, of

a tongue, a spring-head having a concave un- 8. The combination, in a tongue-s11 )port, of a tongue, a colter-wheel and two spring-arms connecting the tongue with the colter-wheel the connection between the spring-arms and the colter wheel comprising a bnsl 1 i ng through the wheel and a spindle passing through the bushing, the spring-mans being fastened to the ends thereof. 6. The combination, in a tongue-support, of
